용수 재이용을 위한 하수처리수 관개 후 논에서의 지표성 미생물의 거동
Indicator microorganisms concentrations change after irrigation of wastewater treatment effluent in paddy field for water reuse
초록
The objective of this research was to examine the significance of change to indicator microorganisms (TC, FC, and E. coli) in the paddy field and repair of UV disinfected secondary effluent. Average concentrations of Microorganisms were maintained by more than about 1,000 MPN/100mL in paddy field after irrigation. Microorganism repair was evaluated in relation to UV dose in photoreactivating light and dark. In addition, a significant inverse relationship was found between UV dose and repair of indicator microorganisms when the research of wastewater was conducted in the condition of low and high UV dose.
